TDR (time-domain reflectometer) - Answer -D. TDR (time-domain reflectometer) A technician is installing a cable run from the batteries to the main DC panel board on a boat as part of a refit. The boat has a 12-volt system and the distance form the panel to the batteries is 15 ft. The maximum current draw from the panel is calculated at 90 amps. What guage cable should be used (minimum)? - Answer -0 AWG DC grounded conductors on new boats that are also equipped with AC systems should use what color insulated wire? - Answer -Yellow What is the smallest guage wire allowed for unsheathed wire runs through the boat? - Answer -16 AWG T or F: Compared to deep cycle (house) batteries, cranking batteries will have thicker lead plates to facilitate the higher, short-duration current draws. - Answer -False. Start batteries have a greater number of thinner plates within each cell. Which type of battery generally recharges faster? Deep cycle or cranking? - Answer -Cranking What tool and common household staple are used to clean battery terminals? - Answer -Wire brush and backing soda. Why might a fully-discharged wet-cell type battery freeze? - Answer Most of the sulfuric acid has been absorbed into the lead plates, leaving mostly water in the electrolyte. Batteries must be secured to prevent movement of more than ______ inches in any direction when a pulling force of _____ or _____, whichever is less, is applied through the center of gravity of the battery for how long? - Answer -1 inch, 90 lbs or 2x the battery weight, for 1 minute in each direction. T or F: it is ok to install batteries directly below an uninterrupted fuel Need assistance on Online classes, Exams & Assignments? Reach out for instant help!!
